DAMPER-REGULATOR.

To all whom it may concern Be it known that I, Ina Gr. WAGNER, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Damper-Regulators, of which the following is a specification, reference being had therein to the accompanyino' drawing.

This invention redates to a new and improved apparatus for regulating dampers.

An object of this invention is the provision of a means for regulating dampers, which is so constructed that they can be automatically operated at predetermined periods.

Another object of this invention is the provision of means whereby a series of dampers can be simultaneously regulated.

Still another object of this invention is the provision of a device adapted to be actuated through the. medium of a clock to oper ate a series of cables, which are connected to a plurality of dampers, whereby the latter will be regulated at predetermined in tervals.

A further object of this invention is the provision of a device of this nature, which will be comparatively simple and inexpensive to manufacture, reliable and efficient in use, and readily operated.

\Vith the above and other objects in view, this invention resides in the novel features of construction, formation, combinations, and arrangements of parts to be hereinafter more fully described, claimed, and illus trated in the accompanying drawings, in which Figure 1, is a side elevation of my invention. Fig. 2, is a front elevation of a portion of the furnace shown in Fig. 1. F ig. 3, is a detail view of the operating mechanism shown in perspective. Fig. 4, is a detail perspective view of the furnace door operating means.

Referring to the accompanying drawings by similar characters of reference, throughout the several views, the numeral 10, designates generally a portion of a building in which are illustrated a wall 11, the floor 12, and cellar 13. A shelf 14, is secured, to the wall 11, above the floor 12, and upon the shelf, in spaced relation to the said wall 11, is fastened a clock 15, from which extends an operating shaft 16, the same being oper- Specification of Letters Patent.

ated by the interior mechanism of the clock 15, which forming no partof the invention, is not shown. This shaft 16, is journaled upon the opposite sides of its crank portion, in bearings 17.

A stove 18, rests upon the floor 12, adjacent the wall 11, and is equipped with the usual front draft door 20; while disposed within the cellar 13, is a furnace 21. This furnace 21., like the stove 18, is provided with a flue 22, in which is located adjacent the lower end thereof, a damper 23; while a similar damper 2 1, is provided at the lower end of the said furnace in its forward side.

The furnace 21, above the damper 24k, is formed with a door opening 2:, upon one edge of which is secured a pair of cars 26, between which is hinged the door 27. This door 27 is made at or the usual type, and is supplied with the rotating damper 28.

A ti -shaped clamp 29, is secured to the lowermost of the cars 26, by the set screw 68, and supports a horizontally disposed stationary arm 30, upon the forward end of which is mounted a pulley 31, above which is secured, to the under side of the floor 12, a similar pulley 32, over which passes a cable 33, the adjacent end of which is secured to a lever as shown at 3 1, to operate the before mentioned door 27. Branch cables 35, and 36, are secured to the cable 33, as shown at 37, and are attached as at 38, to the damper 28, and damper 2%, respectively. 1i supporting plate 39, is secured to the adjacent portions of the wall 11, and floor 12. This plate 39, has pivotally supported thereto, a lever 41-0, to the free end. of which is secured a connecting means 451, which is attached at its opposite end to the crank of the shaft 16. The means all, operates through a sleeve 1-2, which is connected at its terminals to the floor 12, and shelf 1.4. A shaft 43, is mounted in the central portion of the plate 39, and has rotatably mounted thereon a pair of grooved pulleys 44, to which are attached as at 15, the cables 33, and 59, respectively. A double pulley at, is secured to a convenient portion of the floor 12, and over one section of this 1 pulley passes a branch cable l7, the same being attached to the cable 33, between the said pulley 1-6, and the plates 39. A weight 48, is fastened to the lower end of the cable 17 while a cable 49, which is secured to the Patented Ari 26,1913.

weight- 48, passes over the opposite side of the double pulley L6, and is attached to the damper 23.

A latch 50, is pivoted as at 51, to the plate 39, and the upper end of this latch is arranged to engage a stop 52, formed upon the lever 40. The lower end of this latch 50, is forked as at 53, to receive a pin 54, which projects from the adjacent side of one of the pulleys The cable 59, is attached to one of the pulleys 44, and makes a complete wrap around thepulley, and to the end of which is secured an operating weight 57, which serves, when the latch is released, to cause the rotation of the pulley 44, until limited by the door 20, being closed. The cable 33, is secured to the other pulley 44-, in the same way. The doors 20, and 27, are closed by the action of a lever 34, which is mounted on the door pin 64, and has an arm 63, bearing against the door; while the dampers 23, 2a, and 28, are retained closed by gravity.

The operation of the device is as follows :The cable 33, is wound upon the pulley at, against the weight 5'7, which permits the damper 24, to close, and the dampers 23, and 23, and the doors 20, 23, and 27, to remain closed. The pulley eat, is held in this position by the latch 50, which contacts with the stop The clock 15. is then set so that the shaft. 16, will raise the lever 40, through the medium of the means ll, at a certain time, which obviously permits the rotation of the pulley. This partial rotation of the pulley causes the cables 33, 35, 36, a7, and 59, to move their respective doors and dampers to their opposite positions. A here shown, there are employed two pulleys 4st; one to operate the dampers and doors of the furnace 21, by the cable 33, and the other to operate the door of the stove 18, by the cable 59, but either may be dis pensed with or more may be added as desired. As the latch mechanism operates directly on the rear pulley 44, means must be employed to operate the forward pulley as well; and for this purpose is employed the stop pin 65, rigidly secured to the side of the inner pulley 44, and the pin 66, rigidly secured to the inner side of the outer pulley and in the path of the pin and an ad justable pin 67, secured to the outer pulley and also in the path of the pin 65; and in this manner, when the inner pulley is re leased, both pulleys revolve; and when the device is being set by the cable 59, the pin 67, engages the pin 65, revolving the inner pulley 44, in the opposite direction, setting the same, and then assumes the position shown in Fig. 3, and when set by the cable 33, the pins 65, and 66, contact as shown in Fig. 3, to set the inner pulley.

It should be understood in this connection, that various minor changes in the details of construction can be resorted to within the scope of the appended claims, without de parting from or sacrificing any of the advantages of the invention.

From the foregoing disclosures taken in connection with the accompanying drawings, it will be manifest that an apparatus of the class described, is provided which will fulfil all of the necessary requirements of such a device.

Having thus fully described this invention, what I claim as new and desire to protect by Letters Patent is 1. A damper regulator comprising in combination with a damper, a support, a shaft projecting therefrom, pulleys rotatably mounted thereon, pins projecting from said pulleys, and engaging each other, a cable wound upon each of said pulleys; said cables being attached to the pulleys and making a complete wrap around the same, a weight attached to the cable for rotating the pulleys, a cable connecting the pulley and damper for operating the latter upon the rotation of the pulley, a latch pivoted to the support, said latch having a forked end, a pin extending from the pulley and engaging the forked end of the latch, a second pin eX tending from the support to contact with the latch, a lever pivoted to the support, a stop formed upon the lever to engage the latch, and means for raising the lever and ieleasing the latch and permitting the rotae tion of the pulley to move the damper.

2. The combination with a furnace having the usual door opening, and ears attached thereto, a door hinged to said ears, a clamp secured to one ear, an arm carried by the clamp and extending from the furnace, a pulley supported by the arm, a. cable attached to the door and operating means passing over the pulley, a time controlled operating mechanism, and the said cable being attached to the said mechanism.

In testimony whereof I affix my signature in presence of two witnesses.
